IMPROVEMENT IN CLUTCH MECHANISM FOR HARVESTERS.

The Schedule referred to in these Letters Patent and making part of the Sams.

To all 'whom 'it may concern:

Be it known that I, WILLIAM MICHAEL of Murrysville, in the county of Westmoreland and Stat-e of' Pennsylvania, have invented a new and useful Improvement in Mowers and Iteapers; and I do hereby declare the following.,7 to be a full, clear, and exact descriptionoi' the same, reference being had to theaccompanying drawing forming part of this specification.

Thisinventiou relates to harvesters, and consists in au improvement in operating the clutch mechanism, which throws the cutters in and'out of gear with the actuating power.

Figure l represents a' longitudinal, and

Figure 2 a transverse section of those portions of harvesters to which my improvement is attached.

K K represent loose sliding crabs, held in conjunction with the corresponding stationary ones, I I, by the springs M M.

L L are levers, pivoted to the frame A, and having forks on their lower ends, which grasp the recessed crabs K, and slide them out of connection with crabs I.

rlhe sliders K are attached, by spline and feather,

'or in any other suitable manner, to thcir'shaft, H, while the stationary crabs I and spurs G turn loosely on said shaft, except when I and K are together.

N N represent supports,against which the springs M are pressed by the levers.

O O are flat toggle-arms, turning .upon a joint at one end, and pivoted to the ends of levers L L, at equal distances from said joint. These toggles are placed within convenient reach ofthe driveis feet, so that, without relinquishing his hold upon the drivingreins, he may be able to operate the clutches at any time desired, and almost instantaneously.

Having thus described all that is necessary to a clear understanding of my invention,

What I desire to protect by Letters Patent is The lat toggle-arms O O and levers L L, in conibination with spring-clutches K M, arranged as and for the purpose described.

. WILLIAM MICHAEL.
